To a column permanent mold having a T-shaped protrusion therein.

The formwork is a structure temporarily installed to make concrete having fluidity in a reinforced concrete structure or a steel-reinforced concrete structure construction in a predetermined shape and dimensions. Formwork is needed for a short period of time until the concrete is cured to some extent. It is a construction material that will be removed after curing of the concrete. The installation and dismantling of the formwork is a very large part of the cost and time It is a cumbersome process. Particularly, because of the use of large rigid and low-cost mold materials, the formwork weight is considerable, and there is a risk involved in assembling and disassembling heavy materials at high places.

Conventionally, various materials such as plywood and iron plate are used as formwork materials, and they are usually composed of a clay board which is in contact with unplasticized concrete and struts, a wedge, and long settlement supporting it. In particular, iron formwork is relatively heavy, so it needs to be assembled and disassembled with mobile equipment such as a crane, the initial investment cost is high, and there is a considerable burden of volume and weight, such as using angles as a wale.

As a background of the present invention, there is a patent publication No. 1998-028581 entitled "integral column formwork" (patent document 1). This patent discloses a so-called " one-sided molded steel plate " in which several embedding ribs are attached and fixed in a longitudinal direction at a predetermined position on an inner surface extending in a predetermined cross-sectional shape, And the other molded steel plate is formed to be integral with the concrete filled in the inside where the one-side molded steel plate and the other-side formed steel plate are assembled to each other. , Which is used to form a mold using a molded steel plate and to form a column integrally with the concrete laid inside.

However, this patent requires a separate embedding reinforcement on the inner side of the steel plate, which is not only difficult to manufacture in the factory, but also has a problem in that it is not easy to fix the steel bars formed perpendicularly to the steel bars. So that it is difficult to fix the steel plate between the steel plates. In addition, there is a problem in that concrete is poured into the steel plate and the member is removed after curing.

In addition, this patent has a problem that a separate reinforcing member is not formed therein, and therefore, when a large pillar is formed, it can not be used for a large pillar due to expansion or breakage of a molded steel plate used as an outer pillar.

In addition, this patent constitutes the formwork as a steel plate. In general, the formwork made of wood is different from the form in which the surplus water is evacuated and molds to a certain degree, and the formwork made of the steel plate is filled with surplus water in the formwork. There is a problem in that the deterioration is likely to occur.

The angle member 20 is formed of a metal plate.

Since the molding body 10 forms the outer shape of the column, it is formed so as to have a rectangular cross section by joining a plurality of molded steel plates 11 so as to have the same shape as the cross section of the column. The molded steel plate 11 includes a shell plate 111, a vertical stone plate 112 extending vertically at one end of the shell plate 111 and a plurality of vertical plates 112 extending in the same direction as the outer plate 111 The plurality of molded steel plates 11 are connected to each other so that the outer shell plate 111 forms the respective sides of the column and the vertical stone plates 11 of the molded steel plate 11 adjacent to each other 112 are interposed so that both side vertical stencil prints 112 and horizontal stencil prints 113 are joined so as to protrude in a T-shape into the column end face.

The length of the molding body 10 may be different according to the length of the column, and the size of the two-layered and one-sectioned structures may be used for convenience of construction.

The mold body 10 constructed as above is assembled so that the prefabricated main ropes 3 and the reinforcing bars 4 are positioned inside, and the concrete is installed in the inside so that the pillars can be formed. Even if the formwork body 10 is formed into a long length by increasing the rigidity of the formwork body 10 by continuously joining a plurality of molded steel plates 11 without forming the formwork body 10 into a single steel sheet, So that it is possible to prevent the occurrence of deformation of the metal plate. A plurality of vertical stone papers 112 and horizontal stone papers 113 protrude in the form of a T in the cross section of the mold body 10, And is designed so as to transmit shear stress against the horizontal shear force between the form body 10 and the concrete and at the same time ensure the integrity. The vertical stencil publication 112 and the horizontal stencil publication 113 are also spaced apart to maintain a constant coating thickness to maintain a constant spacing between the inner surface of the formwork body 10 and the strip bar 4 or main stream 3. [ Let's play the role of ashes.

The transverse steel angle 40 has a bifurcated cross- And the end portion is coupled to the inner surface of the outer shell 111 of the molded steel plate 11. A coupling groove 422 is formed in the horizontal portion 42 for receiving the vertical projection 112 and the horizontal projection 113 of the forming member 11 and the channel member 30, The upper and lower concrete are not disconnected by the transverse steel angle 40 when the concrete is poured into the molding body 10 and the concrete flows into the concrete flow hole 421, So as to serve as a shear connection member.

The transverse steel angle 40 is a means for simultaneously restraining a plurality of molded steel plates 11 in the transverse direction to prevent widening or deformation due to side pressure or the like of concrete laid in the inside and also to prevent buckling by reducing the width width ratio .

Since the molding body 10 composed of a plurality of molded steel plates 11 is used as a mold for a column, the molding body 10 is formed to have a long length, and a longer length tends to cause buckling. When the transverse steel angles 40 are configured to be coupled at regular intervals in the height direction of the formwork body 10, buckling of the formwork body 10 can be prevented.

A plurality of engaging holes 411 are formed in the vertical portion 41 of the transverse steel angle 40. The joining hole 411 is a means for joining the main bar 3 or the band bar 4.

FIG. 5A is a side cross-sectional view showing a combination of the column permanent formwork of the present invention and a bar steel bar, and FIG. 5B is a flat cross-sectional view showing a connection with a cast iron bar.

The outer shape of the outer plate 111a, And a horizontal stone plate 113a horizontally extending in the same direction as the outer plate 111a at the extending end of the vertical stone plate 112a, The vertical stone punch 112a is engaged with the vertical stone punch 112 of the two-sided molded steel plate 11 and is engaged.

Further, since the width of each side of the column is widened, the width supporting channel 60 may be configured to connect the channel member 30 formed at the center of each side in order to maintain the rigidity of the molding body 10.

The width support channel 60 is formed in a U-shaped cross-sectional shape. The width of the support channel 60 can be formed by forming a steel plate, but the channel and the unit cost can be reduced by using a channel having a C-

The coupling of the width support channel 60 and the channel member 30 is achieved by welding the ends of the width support channel 60 to the channel member 30 with the openings of the width support channel 60 facing upward or downward, The width of the width support channel 60 may be smaller than the width of the channel member 30 so that the end of the width support channel 60 is inserted through the opening of the channel member 30 to be coupled.

The width support channel 60 may be reinforced to warp warpage of the formwork body 10 and serve as a width support for maintaining the width of the inside of the formwork body 10 at the same time as lateral reinforcement.

7 is a perspective view of a permanent column form having a T-shaped protrusion therein using a molded steel plate according to another embodiment of the present invention.

The present embodiment further comprises a surplus water outlet (70).

Concrete placed in the mold body 10 contains surplus water. Concrete in the cement system (CaO) requires water (H 2 O) for curing. At this time, the water required for pure curing only is about 25% of the weight of cement. However, in general, The water cement ratio used for mixing of concrete is about 65% because of having fluidity (securing of workability). Water except water that is necessary for hydration reaction is called surplus water. It should be evaporated with concrete hardening.

In general, a die made of wood has a problem in that the strength of the concrete after curing is lowered because the surplus water is evaporated in the form of a certain amount, unlike the case in which the surplus water is evaporated. (70) is designed to solve this problem.

The surplus water outlet 70 is composed of a surplus water discharge hole 71 punctured in the shell plate 111 of the molded steel plate 11 and a mesh 72 attached to the inner surface of the shell plate 111, A high quality concrete strength can be obtained by discharging unnecessary surplus water from the concrete through the surplus water discharge hole 71 while preventing the cement or the aggregate from being separated by the mesh 72 constituted by the water. The surplus water outlet 70 may be formed under the outer skin plate 111 of all the molded steel plates 11 constituting the molding body 10 as shown in FIG. They may be formed on the one side steel plate 11 of the molded steel plate 11 adjacent to the body 10 in the order of the circumference of the main body 10 and below the steel plate 11 so as not to be formed on the other side steel plate 11. 7A and 7B illustrate that the surplus water outlet 70 is formed in two rows in the lower part of the molded steel plate 11, the present invention is not limited thereto and may be configured to have various rows and columns, It may be formed at regular intervals over the entire length of the molded steel plate 11 as shown in Fig. As shown in FIG. 7D, the position and number of the surplus water discharge ports 70 may be variously formed. As shown in FIG. 7D, one side of the molded steel plate 11, which is adjacent to each other in the order of the periphery of the molding body 10, And the other formed steel plate 11 is formed over the entire length of the outer plate 111 in the order of the outer plate 11 and the outer formed plate 11.

As described above, according to the present invention, it is possible to manufacture a mold by assembling a molded steel plate divided so as to reinforce the inner surface with a built-in angle and a channel, so that it is very easy to assemble and install on-site, And it is possible to improve the unity with the concrete inserted in the inside. It can be used as a column formwork, but it can be used as a concrete form after the concrete is hardened, It is possible to use it as an exterior material without removing it, and it is possible to further reinforce it through the width support channel, so that it can be applied to medium and large columns. Particularly, since the surplus water is discharged to the surplus water outlet while the form is formed of the steel plate, there is a useful effect of solving the problem of the decrease in the concrete strength due to the surplus water.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art in light of the above teachings. will be. The invention is not limited by these variations and modifications, but is limited only by the claims appended hereto.
